Both the reason and duration are unknown at this time, although head coach Paul Maurice told TSN 1290 that Byfuglien is "going to be fine," adding that it's "nothing sinister," according to The Athletic's Murat Ates.

Byfuglien was productive during an injury-riddled season in 2018-19, tallying 31 points in 42 games.

With fellow defensemen Jacob Trouba, Tyler Myers, and Ben Chiarot departing this offseason, the Jets are counting on a big campaign from Byfuglien to help them return to the playoffs.
